Lehr tunnel Primary tunnel I (Fig. 1) has heat insulation jacket 2 and way 3 therethrough. This tunnel is carried by depending legs 4 mounted on rollers 5 so the general structure is portable or shiftable. In this tunnel is primary mesh-conveyor belt 6 having its upper reach (Figs. 9, 11) supported by grids I and cross bars 8 at its higher temperature portion. Depending partitions 9 may be controlled as to their position to retard ventilation, which ventilation is further controlled by dampers ID in flues I I leading to ducts I2 to pass away by stack I3 as fixed to the shielding means in the temperature control (Fig. 1).

'This insulation jacket 2 may be along this tunnel I as the temperature drops from that of reception in the instance of handling glass ware to be annealed, and as such insulation wall is reduced, there may be open top It with control leaves I5 thereover for a section and then merging into open way I6. Associated with the shielding means in this temperature control there may be burners H at firebox I8 (Fig. 11), say for gaseous or oil fuel, thereby developing temperature for the closed receiving end of this tunnel 5 of say around 1100 R, which may he stepped down say to 950 F. in the region of the first flues, thence in stages to 800 F., 650 F., and down to the region of 300 F. or 400 F. near the leaves I5. This temperature control may be deter mined according to the mass of the Ware and sufficient body therein to sustain such under the transit conditions. As the temperature is reduced, instead of the grid and bar supports for 5 the conveyor in the high temperature region,

there may be rollers I9 (Fig. 3) for this endless conveyor toward discharge or delivery end 20.

The return or idle reach of this conveyor belt 5 may be carried below the upper reach by rollers 2i to pass guide roller 22 (Fig. 11) to primary conveyor lehr terminus roller 23. The shafts 24 for the rollers 22, 23, may be open or hollow, connected by side duct 24' (Fig. 4) with blower 25 for holding the temperature of these shafts down sufliciently to retain rigidity therefor in the lehr operation herein as a continuous drive.

Lehr drive Adjacent the discharge end from this tunnel, there may be located below the lower reach of this conveyor belt 6, motor 26 (Figs. 2, 3) having shaft 21, on which is mounted sprocket wheel 28 efiective through sprocket chain 29 to drive sprocket wheel 30 on shaft 3I of variable speed transmission device 32. Protruding from the side of the conveyor is handle 313 effective to operate shaft 34 and adjust this variable speed device in the desired ratio. Therefrom the transmission is through speed reduction mechanism 35 to shaft 36 having sprocket 31 from which extends sprocket chain 38 to sprocket 39 on shaft 40. Pinion 4I on this shaft 40 is in mesh with pinion 42 on shaft 43 and pinion 44 on shaft 45. On the shafts 43 and 45 are cylindrical rolls 46 having thin rubber coating 41 as a friction holding means for the wraps of this wire mesh conveyor belt 6 in passing for large angle of contact about the upper roller 46 on the shaft 43, thence about roller 48 to wrap about the roller on the shaft 45, thence about roller 49. These rollers 48, 49, are in frame 50 mounted in slide way 5| and may be effective as an endless conveyor tightening device as adjusted relatively to the driving rollers on the shafts 43, 45.

This frame 50 at each side of the lehr has internally threaded eye 52 (Fig. 2) with which may engage threaded stem 53 terminating in worm pinion 54 in mesh with worm 55 on transverse 45 shaft 56 protruding to have handle 51 so that such may be manually operated in providing slack or taking up slack'in the conveyor 6 as may be proper for operating conditions.

In view of the width of this conveyor belt, 50 which may be say up to 6 feet or more as desired, question of alinement between the sides of thebelt may arise in the overall length, especially when such may be in the range of upward of '75 to 100 feet or more. Accordingly, 55 the shaft 43 has bearings 58 with internally threaded bosses 59, with which may coact bolts 60 for letting out or drawing in one end or the other of this shaft 43, thereby to avoid any skew travel tendency in the conveyor primary lehr 0 carrying belt.

Formed ware supply Forming machine 6| (Fig. 6) may have delivery arm 62 for depositing ware 63 on convey- 65 or 64. There may be-variance in the height as well as other dimensions of this ware, and it is a factor of importance in the installation herein disclosed to care for such range of variation as well as take care of the current output of the glass forming machine or machines. The continuous travel of the lehr primary conveyor belt may accordingly be adapted to the rate of supply as well as the interval for annealing operation, which for greater mass ware is accordingly less than for thin walled or lighter ware. The

drive for the lehr conveyor has its range of control. The lehr charging cross-conveyor has drive for adapting to the supplies thereto and according to the requirements sought. The supply is adaptable for conforming to the formed ware supply and transit therefrom.

The supply device proper embodies independent power driven mechanism of wide range of adaptation. To this end, base 65 (Figs. 5, 7, 8) has screw 66 for adjusting height, as carried thereby, of brackets 61. Suspended from this bracket 61 is motor 68 having shaft 69 with change speed device 10 therefrom having control 1! therefor. From this change speed device 10 there is speed reduction device 12 having shaft 13 with sprocket 14 thereon connected by sprocket chain 15 with sprocket wheel 16 on shaft 11 having sprocket wheel 18 to drive conveyor belt 64 as carried by the bracket 61 and extending about idler 80. This bracket 61 above the adjusting screw 66 has hingeshaft 8|. This bracket 61 has fixed therewith and extending from shaft 8| arm 82 carrying adjusting screw 83, effective upon section 84 hinged on the shaft 8I to rock such section 84, together with the conveyor 64 for determining different relative vertical height positions; while the supply end of this conveyor adjacent the roll may maintain the desired receiving position from the ware forming machine. This adjustment of the height for the roller 80 is determined by nut 85 on the stem 66. The shaft 11 extends outward from the conveyor belt 64 to carry worm 86 in mesh with worm wheel 81 on vertical shaft 88 carrying transfer disk 89, thereby driven from this supply conveyor drive.

Adjustably fixed with this transfer disk 89 by clamping screw 90 (Fig. 4) is slotted arm 9| carrying guide 92. This guide, in cooperation with complementary guide 93, may determine the line of travel of ware from the supply conveyor 64 past and over the transfer disk 89 to cross-conveyor 94. The adjustment by the screw 83 (Fig. 7) effects the shifting not only ofv the supply conveyor discharge end but the transfer disk 89 to bring such as a unit into the desired relative leveling relation with the cross-conveyor 94, so that the ware transit is continuous with appropriate common plane for such passage.

Adjustable receiving end of tunnel The lehr I, remote from its delivery end 20, has joint (Figs. 1, 9, 10) for relatively vertically adjustable section 96 with shorter mounted roller 91. In practice adopted hereunder, for a 9-inch swing, the drop from, alignment or hori-- zontal is approximated at 4% inches, so that this roller 91 may be in proper shifting position for the lehr unit at the lower operating position. However, for holding or shifting there are interposed bases 98 (Fig. 11) having stems 99 downwardly shiftable by transversely extending drive devices I00, so that these may be operated simultaneously for bringing the receiving end of the lehr into proper or required height position as to range for ware to be received as supplementing the limits or avoiding adjusting for limit as to the supply conveyor.

Lehr feeding cross-conveyor This adjustable tunnel section 96 (Figs. 4, 11) has mounted thereon motor IOI. having shaft I02 with pulley wheel I03, from which extends belt I04 to pulley wheel I05 mounted on shaft I06 to change speed device I01, adjustable by hand wheel I08. This change speed device I01 has therefrom shaft I09 to speed reduction device H0 effective to drive pinion HI in mesh-with gear H2 on shaft H3. This shaft H3 carries pinion H4 (Fig. 14) in-mesh with gear H5, on shaft H6, which extends laterally over the side of the lehr to carry bevelgear H1 in mesh with bevel gear II8 on vertical shaft H9; at the lower end effective through bevel pinion I20 (Fig. 15) to drive bevel pinion I2I on shaft I22 carrying pulley I23, driving cross-conveyor 94 (Fig. 16). Thi cross-conveyor 94 extends transversely through the lehr and has at its other end pulley I25 mounted by bracket I26. a

At the lower reach of this conveyor belt is located automatic belt tightener comprising shaft I21 carrying guide roller I28. This shaft. I21 has thereon arm I29 carrying roller I30 to engage the opposite side of the conveyor belt. Fixed with this arm I29 is quadrant I3I having sprocket chain I32 therefrom to weight I33, tending normally tolift the roller I30 to take up slack in the lower reach of this transverse or cross-conveyor belt 94.

There is located below this cross-conveyor directing brackets I34. (Fig. 11) for maintaining coplanar registry. of the upper reachof this con-. veyor belt 94 with the primary conveyor 6 of the lehr. Additionally, there is provided manually controllable valve I35 for burner I36, effective to supplement the primary, burner or adjustable temperature control I! above the lehr conveyor. This is a safeguard. against undue chilling of the entering ware.' Access to the lehr i at this closed end is effected by grasping handles I31 to remove insulation blocks I38. The variable speed drive I01 may be adjusted for affecting the speed of this cross-conveyor in desired rate of travel relatively to the supplied ware and its character, for the coordinately independently adjusted and independently driven conveyor 6 of the lehr. Thereby it is practicable for maximum capacity consistent with the treatment to be efiec-ted. Also, there is possibl range for maximum capacity of output and minimum expense.

Within the lehr transfer This transfer is synchronized with the crosslehr conveyor. This synchronizing is effected by having common drive therefor. Accordingly, from this shaft H3 (Figs. 4, 11, 14) the pinion H4 is in mesh with gear I39 as well as the gear I I5. The gear I39 is on shaft I40 and is effective to drive mutilated companion gear MI. The mesh or toothed portion of this gear MI is effective at pinion I42 on shaft I43 fixed for rotation in bracket I44 mounted on the lehr section 96.

Rotatable with this pinion I42 is sprocket wheel I45 (Fig. 18). Adjacent this sprocket wheel I45 is single tooth ratchet disk I46 adapted to be engaged by pawl I41 (Fig. 17) having eccentric fulcrum mounting I48 (Fig. 19), angularly ad-' justable as a crank on bearing I49 by clamp nut I50.

Fixed with this pawl I4! is arm I 5I (Figs. 17, 19) engaged by compression spring I52 on bolt I53 as holding means adjusted-by nuts I54, yieldably urging the pawl I41 into engagement with the tooth of the ratchet I46. This sprocket wheel I45 is in mesh with endless cycle-providing rack I55, herein shown as an endless sprocket chain mounted in frame I56. The tooth relationship between the sprocket wheel I45 and the teeth I55 of the rack effect a definite predetermined relation, which as to blank I51 of the mutilated gear I4 I in the set-up herein, positions the member to be moved at a down position for rest along the cross-conveyor on the side of the cross-conveyor away from the lehr.

Frame I56 has therethrough vertical guideway I58 (Figs. 18, 20) and, at right angles thereto, horizontal guide-Way I59. Bar I60 in the guide-way I58 provides vertical direction control for this slide or shiftable frame I56; This guide bar I60 (Figs. 4, 11, 14), as fixed with the frame I44, at its upper portion carries sprocket wheel I6I about which extends sprocket chain I62 connected to the slide I56 on one side. This sprocket chain I62, passing about the sprocket wheel I6I, on the opposite side carries counterweights I63. There is thus provided a balancing means for the transfer member vertically which has the lift and descent control through the pair of guides I60. In the horizontal guides I58 are guide bars I64 having connection I64 (Fig. 20) with the rack frame I56, horizontally as to the Vertical guide I69. These guide bars I64 have, as protruding over the closed end of the lehr, depending members 165 with inwardly extending portions I66 through slots I61 (Fig. 14) to carry inside the lehr depending plate or pusher I68 (Fig. 11)

In'this descent as determined by the rack I55, this pusher I68 may approach the bottom of the lehr as determined by the plane of the conveyors 6, 94. This position may beat a desired location near the bottom of the Ware as determined by flange I69, so that in engaging the ware and pushing such transversely off the conveyor 94 to ride on the conveyor 6 as in a common plane, the ware may not tend to tilt in this line of travel as effected by the movable rack I55 in controlling this depending frame member or transfer pusher. In this push over off the cross-conveyor 94, the distance is such beyond the width of this conveyor 94 that the vvare is effectively delivered to the conveyor 6. The speed of such delivery is such that incoming ware is not retarded by this movement. Furthermore, there is recover travel for this pusher only after the lift action thereon, as effected by the rack I55, is to a height clear of the incoming ware for this pusher side I68, before such is retrieved backward toward the closed end of the lehr and then allowed to descend on the side of the conveyor 94 away from the lehr conveyor 6; and, as in such position, may have a period of rest for an interval to allow the incoming ware again to supply articles for the transverse width of the. conveyor 6. While this shifting may be continuous, it is desirable that the pusher transfer be at a speed greater than the supply rate forincoming ware so that, in transferring a push over or group from the conveyor 94, there is not an interception of flow or travel of incoming ware. There is thus provided speed up for the push off. This variable velocity from a constant speed drive is adapted in practice to develop a period of rest for this pusher of as much as one-half the time interval therefor. During this period there may be an accumulation of Ware to complete the charging quantity to be pushed off the cross-conveyor 94.

At this speed of transfer, it is important there be not hazard toward upsetting the ware. Ac-

cordingly, depending portion of the pusher from the bar I64 may have notches I10 with which may engage cross hook I1I to carry steadying device I12 in a desired height position on the opposite side of the ware from that receiving the pushing contact. It is thus seen that the vertical 5 adjustment for this adjustable section 96 of the lehr is one nicely effected as a unit with this cross-conveyor 94. Accordingly, in caring for different heights of ware, whether above or below the plane of the main lehr conveyor 6 as away from the section 96, there may be adjusted relationship thereto for the cross-conveyor. Furthermore, the driving ratio between this cross-conveyor and the transfer are nicely synchronized 15 from a common source. These predetermined controls are factors in efficiency in operation to avoid hazard to the ware, even at a high rate of output, say in a range of twenty-five to over forty articles per minute, which articles may be sup- 20 plied in a row by the conveyor 94.

Operation In practice hereunder, the lehr may be brought to desired relationship with the ware forming g5 machines. Such major relation may have supplemental adjustment effected by the supply conveyor and its transfer disk placed in the desired angular relation to takecare of height condition and speed of production as to the rate of travel. 30 With such adjustment for the supply conveyor 64, the cross-conveyor 94 may have its speed adapted thereto for the desired proximity in placing the ware together with the adaptation thereof to height. This control spacing may be such 35 as to clear the sides of the lehr at the time for pushing off this cross-conveyor 94 to the primary conveyor 6 in the lehr. With the ware as traveling into the lehr and the common drive for the cross-conveyor and the transfer within the lehr, 49 such are as adjusted for receiving the ware from the supply conveyor coordinated with the lehr conveyor in completing the feeding transfer automatically. The range of adjustments for speed and temperature are effective in output control and output timing. The lighter walled ware may be more rapidly annealed and accordingly with speed-up in the conveyor, while the heavier walled articles may require less speed with corresponding variance in temperature control. As 50 the cross-conveyor 94 is charged for the width of the lehr with incoming ware from the forming machine, the sequence is such that the pusher I69 will thrust such ware quickly as from such conveyor 94 and as steadied by the member I12 55 from this conveyor 94 to the conveyor 6. At once this delivery is made to the moving conveyor 6, the rack I55 effects ascent of this pusher and its steadying member I12 clear of the ware, then receding of such to above the original position, 60 and then descent to position of rest for the following charge group of articles of ware. In this position of descent, the pawl I41 holds the shaft I43 against shifting until the time sequence as determined by the mutilated portion I 51 of the 65 ear MI. The ware accordingly travels through the lehr and has its temperature reduced gradually for the finished ware to be delivered therefrom. The lehr conveyor 6 is adjusted as to alignment, tension and speed and the heat con- 70 trol.

The pawl I41 (Figs. 1'1, 18) so locks the angular relation between the toothed gear I M on the shaft I40 as to the pinion I42 on the shaft I43 that there is maintained timing or angular rela- 75 tion therebetween during the interval of rest when the shaft I40. rotates thegear MI in the non-driving position or with the mutilated portion I51 effective. In practice, this relation, instead of being one-half .mutilated portion-I51, may bemore or less, even to absence. A ratio I 5 as adopted in practice has been for the gear I42 to have fourteen teeth as against the gear I39 having eighty-four teeth. From this it follows thatits companion gear I4I has forty-two teeth effective and the mutilated portion cleared as 0 to forty-two teeth. In this ratio, the rack I55 has had eighty-eight teeth as against twentytwo teeth in the sprocket I45. The functioning has worked out for three rotations of the sprocket I45, notwithstanding its twenty-two teeth to complete a cycle about the eighty-eight teeth of the rack. It is thus seen that the drive from the shaft I40 is a time control determining the sequence for rest or the position along the cycle for this transfer or push-over device.

The placingof the steadying device I12 in position or in shifted position is readily accomplished by pulling out or removing insulation block or door I13 (Fig. 14) thereby giving access along the side of the pusher so'that such may be placed in a different position as to the notches I10 or removed in the substitution of the steadying device to be inserted. As this adjustment is effective, the door I13 is pushed back in position clear of the cross-conveyor 94.

Hub I14 (Fig. 11) for the sprocket wheel I6I is eccentric, having its longer radius side at the down position for the transfer device portions I56, I64. At the lift position, that is, when the rack frame I56 is lifted so that the arm I66 from the pusher is at the high position,- then the unbalanced counterweight I63 has descended, the wheel I6I has rotated 180, and this longer arm from the hub I14 is on the sideof the counterweight I63. justment for this counterweight to be a steadying action in the lifted position for the pull-out and for steadying action in the down position or holding and effective shoving of the Ware.

Supplemental to or in lieu of the aligning 5 means 59, 60 (Fig. 2) the shaft 56 may have sections 56, 56", in alignment with radial clutch member I15 fixed on the shaft section 56' and radially ribbed complementary clutch disk section I16 on the shaft section 56". Spline I11 holds this disk I16 in angular position with the shaft section 56" as locked by set screw I18. Accordingly, upon releasing set screw I18 and sliding this clutch disk I16 clear of the clutch disk I15, the operator at the handle 51 may ef- 55 feet relative angular shifting of the shaft section 56" as to the shaft section 56 in either direction, thereby shifting the shaft 43 into the desired aligning relation for the mesh conveyor 6. Assuch is effected, the clutch disk I16 is re-set 60 into the meshed relation with the complementary section I15 and the set screw I18 effected to lock so that at subsequent operation of the handle 51 there is operated the shaft 56 as a unit for simultaneously effecting the adjustments with the angle of friction automatically effectively holding the parts.

The intermediate pinion 4I between the shafts 43, 45, causes such two live shafts 43, 45, to act on the non-ware carrying side of the conveyor belt 6 in extended arcs of contact for effective tractive effort augmented herein by the coating 41.

Burners I1 (Fig. 11) are primary burners herein as to the combustion chamber I8 with 7 Accordingly, there is automatic ad- 4o down draft induced therefrom by the fines II leading to the ducts I2 and stack I3. This brings the heat in the desired annealing relation for the ware to be tempered or handled. However, in practice there may at times be desired supplemental niceties in temperature control to be effected by the auxiliary burner I36, from which the heat naturally rises to Warm the ware as on the pusher and as passing therefrom to the conveyor 6. This nicety of control is regulated not only as to the control valve I35 but in regulating the amount of such heated draft by the port opening left narrow or wide by shifting the insulation block or partition I19.

In this cycle of the fixed rack I55, the shaft I 33 has protruding therefrom pin I80 (Fig. 18) to ride clear of rectangular frame I8I (Figs. 1'7, 18). There is accordingly a supplemental control. At the corners the sprockets hold this sprocket wheel I against radial shifting. However, as along a straight edge, that is, for vertical or horizontal extent of travel, there might be a tendency from some source of disturbance to shift or prevent or effect travel of the sprocket teeth out of mesh relation. This is precluded because this pin I is in such proximity to the rectangular frame I8l that clearance from such source is not possible. However, if in machine operation there be untoward disturbing condition, the machine is not wrecked thereby, for the pinion I42 has frangible pin I82 (Fig. 18) keying such with the shaft I43.
